Example one
When the common load of a certain 750t/h garbage treatment capacity unit is 90-120% of a rated working condition, the temperature of condensed water at the outlet of a No. 2 high-pressure heater 4 is about 70 ℃, the temperature of condensed water at the outlet of a No. 1 high-pressure heater 5 is about 93 ℃, a low-temperature economizer 11 inlet water temperature adjusting system is formed by a first three-way valve, a second three-way valve, a third three-way valve, a first adjusting valve and a second adjusting valve, and the temperature of a pipe wall is mainly determined by the water temperature of the condensed water when heat exchange is carried out between flue gas and the condensed water in the low-temperature economizer 11. Therefore, the water temperature of the condensed water at the inlet of the low-temperature economizer 11 cannot be too low and should be controlled to be 20 ℃ above the water dew point, the water in the flue gas is higher due to the characteristics of the fuel of the waste incineration unit, the water dew point temperature is estimated to be about 60 ℃ according to the water content of the flue gas, and therefore the water temperature at the inlet of the low-temperature economizer 11 is 80 ℃ at the lowest.
When the unit operates daily, the temperature of the exhaust gas at the outlet of the induced draft fan 12 is between 155 and 180 ℃, and the moisture content (about 20 to 25 percent) and SO content in the exhaust gas at the inlet of the induced draft fan 12 are tested 3 The content (about 0.1-1 ppm) and the flue gas acid dew point temperature estimated according to an empirical formula are between 95 and 110 ℃, and in order to keep a certain safety margin, the outlet flue gas temperature of the low-temperature economizer 11 needs to be controlled to be above 120 ℃;
the temperature of the flue gas at the outlet of the low-temperature economizer 11 is controlled to be above 120 ℃, and the temperature of the water at the inlet of the low-temperature economizer 11 is controlled to be above 80 ℃ by adjusting the opening degrees of the first regulating valve and the second regulating valve;
the water flow entering the low-temperature economizer 11 is controlled by adjusting the opening degree of the third regulating valve, so that the temperature of the flue gas at the outlet of the low-temperature economizer 11 is above 120 ℃.
Tests prove that the temperature of the flue gas at the inlet of the induced draft fan 12 can be reduced to about 120 ℃ from about 155-170 ℃, the actual volume flow of the flue gas is greatly reduced, the power consumption of the induced draft fan 12 is obviously reduced, and the condition that the plant power consumption is overhigh commonly existing in a waste incineration power station is relieved.
